Description

Title of the invention: W / O emulsion comprising a volatile alkane, a non-volatile mixture of C15-C19 alkanes, a non-cyclic volatile silicone oil, a hydrophobic silica aerogel and a silicone emulsifier Technical field

[0001] The present invention relates to the field of care and / or makeup of keratin materials, and aims to propose compositions more particularly dedicated to the care and / or makeup of the skin.

[0002] The skin is not a smooth, solid-colored surface and has reliefs and microreliefs such as pores, fine lines, wrinkles, spots, scars, dry areas, which form a somewhat bumpy surface. Quite often, this surface, with its irregularities, forms a whole that is pleasant to look at, but the irregularities are such that sometimes the surface is considered unsightly.

[0003] Cosmetic makeup and / or care compositions are commonly used to camouflage, smooth and / or unify imperfections in the skin's texture such as pores, wrinkles and / or fine lines and / or scars. In this regard, numerous formulations, solid or fluid, anhydrous or not, have been developed to date.

[0004] The application of a makeup composition such as a foundation is the most effective approach to beautifying uneven skin by hiding spots and discolorations, reducing the visibility of relief imperfections such as pores and wrinkles, and masking spots and traces of acne; in this regard, coverage is one of the main properties sought.

[0005] In the cosmetic field, water-in-oil emulsions, also called inverse emulsions, are particularly appreciated by consumers in the field of foundations, sunscreen products or moisturizing creams, with regard to their cosmetic properties, in particular with regard to their comfort after application which is reflected in particular by a deposit effect after drying that is non-greasy, dry, powdery and at the same time soft. These same inverse emulsions also make it possible to contain a significant quantity of fillers and / or pigments and to obtain good coverage and homogeneity during application compared to direct emulsions. However, such compositions have the disadvantage of generally being difficult to stabilize.

[0006] Skin makeup compositions, especially liquid foundations, generally contain volatile solvents such as volatile silicone oils. cyclics also called cyclomethicones such as octamethyl cyclotetrasiloxane (D4), decamethyl cyclopentasiloxane (D5), dodecamethyl cyclohexasiloxane (D6). They provide a non-greasy, dry, powdery and at the same time soft, like silky touch and promote the spreading of the product on the skin. However, cyclic volatile silicone oils are synthetic polymers of the polyorganosiloxane type which are not biodegradable.

[0007] Care and / or makeup compositions for keratin materials such as skin often also contain fillers.

[0008] By "filler" is meant colorless or white, solid particles of all shapes, which are in an insoluble form and dispersed in the medium of the composition.

[0009] They are used as opacifiers; mattifiers, for a very specific soft and silky touch, to give body or rigidity to the composition and / or softness and uniformity to the makeup.

[0010] Many care and / or makeup products include organic fillers and most often consist of synthetic polymer particles called microplastics.

[0011] According to the definition of the European Chemicals Agency (ECHA), "microplastic filler" means a synthetic microparticle in solid form composed of polymer, the size of which is less than 5 mm, insoluble and non-biodegradable. Microplastic fillers are generally dry and soft to the touch.

[0012] There remains a need to find new formulas for the care and / or makeup of keratin materials in the form of a water-in-oil emulsion without cyclic volatile silicone oil and without microplastic filler having good covering properties to correct imperfections with a homogeneous result, good sensory properties such as ease of spreading, a deposit effect after drying, non-greasy, dry powdery and at the same time soft, and good stability in temperature stability tests.

[0013] Unexpectedly, the inventors have found that it is possible to achieve these objectives with a composition for caring for and / or making up keratin materials, in particular the skin, in the form of a water-in-oil emulsion comprising, in particular in a physiologically acceptable medium: (a) at least one continuous oily phase comprising (i) at least one volatile alkane and (ii) at least one non-volatile mixture of C15-C19 alkanes; and (iii) at least one volatile non-cyclic silicone oil, and b) at least one aqueous phase dispersed in said oily phase

[0014] c) at least hydrophobic silica aerogel particles; and

[0015] d) at least one silicone emulsifying surfactant with HLB < 8.0; said composition not containing cyclic volatile silicone oil or microplastic filler.

[0016] This discovery is the basis of the invention. Objects of the invention

[0017] Thus, a first object of the present invention is a composition for caring for and / or making up keratin materials, in particular the skin, in the form of a water-in-oil emulsion comprising, in particular in a physiologically acceptable medium: a) at least one continuous oily phase comprising (i) at least one volatile alkane and (ii) at least one non-volatile mixture of C15-C19 alkanes; and (ii) at least one volatile non-cyclic silicone oil, and b) at least one aqueous phase dispersed in said oily phase

[0018] c) at least hydrophobic silica aerogel particles; and

[0019] d) at least one silicone emulsifying surfactant with HLB < 8.0; said composition not containing cyclic volatile silicone oil or microplastic filler.

[0020] A second subject of the present invention relates to a cosmetic process for coating, in particular for making up keratin materials, in particular the skin such as the face, hands, eyelids, cheeks, comprising at least: the step of applying the composition, a composition as defined above on said keratin materials. Definitions

[0022] By "physiologically acceptable" is meant compatible with the skin and / or its appendages, which has a pleasant color, odor and feel and which does not generate unacceptable discomfort (tingling, tightness), likely to deter the consumer from using this composition.

[0023] By water-in-oil emulsion is meant a composition comprising an immiscible oily phase and an aqueous phase; the aqueous phase being dispersed in the form of droplets in the oily phase (called continuous) so as to obtain a macroscopically homogeneous composition.

[0024] By “composition without cyclic volatile silicone oil” is meant any composition comprising less than 1.0% by weight of cyclic volatile silicone oil, or even less than 0.5% by weight, or even less than 0.1% by weight relative to the weight, total weight of the composition or even free of cyclic volatile silicone oil.

[0025] By “microplastic-free composition” is meant any composition comprising less than 1.0% by weight of microplastic(s), or even less than 0.5% by weight, or even less than 0.1% by weight relative to the weight, to the total weight of the composition or even free of microplastic.

[0029] By "non-volatile oil" is meant an oil remaining on the skin or keratin fiber at room temperature and atmospheric pressure for at least several hours and having in particular a vapor pressure of less than 2.66 Pa, preferably less than 0.13 Pa. For example, the vapor pressure can be measured according to the static method or by the isothermal thermogravimetry effusion method, as a function of the vapor pressure (OECD standard 104).

[0030] By "non-volatile alkane" is meant an alkane remaining on the skin at room temperature and atmospheric pressure for at least several hours and having in particular a vapor pressure of less than 2.66 Pa, preferably less than 0.13 Pa. For example, the vapor pressure can be measured according to the static method or by the isothermal thermogravimetry effusion method, as a function of the vapor pressure (OECD standard 104) Oily phase

[0066] Water suitable for the invention may also be demineralized water.

[0067] A composition of the invention may comprise water in a content varying from 20 to 50% by weight, and even more preferably from 30 to 45% by weight relative to the total weight of the composition. Hydrophobic silica aerogel

[0068] The composition of the invention contains at least hydrophobic silica aerogel particles.

[0069] Silica aerogels are porous materials obtained by replacing (by drying) the liquid component of a silica gel with air.

[0070] They are generally synthesized by sol-gel process in liquid medium and then usually dried by extraction of a supercritical fluid, the most commonly used being supercritical CO2. This type of drying makes it possible to avoid contraction of the pores and the material. The sol-gel process and the different drying methods are described in detail in Brinker CL, and Scherer GW, Sol-Gel Science: New York: Academie Press, 1990.

[0071] Preferably, the hydrophobic silica aerogel particles used in the present invention have a specific surface area per unit mass (SM) ranging from 500 to 1500 m2 / g, preferably from 600 to 1200 m2 / g and better still from 600 to 800 m2 / g, and a size expressed as volume average diameter (D[0.5]) ranging from 1 to 1500 pm, better still from 1 to 1000 pm, preferably from 1 to 100 pm, in particular from 1 to 30 pm, more preferably from 5 to 25 pm, better still from 5 to 20 pm and even better still from 5 to 15 pm.

[0072] The specific surface area per unit mass can be determined by the method nitrogen absorption method called BET (Brunauer - Emmet - Teller) described in "The Journal of the American Chemical Society", vol. 60, page 309, February 1938 and corresponding to the international standard ISO 5794 / 1 (Annex D). The BET specific surface corresponds to the total specific surface of the particles considered.

[0073] The sizes of silica aerogel particles can be measured by static light scattering using a commercial granulometer of the Master Sizer 2000® type from Malvern. The data are processed on the basis of Mie scattering theory. This theory, which is accurate for isotropic particles, makes it possible to determine, in the case of non-spherical particles, an "effective" particle diameter. This theory is described in particular in the work of Van de Hulst, HC, "Light Scattering by Small Particles", Chapters 9 and 10, Wiley, New York, 1957.

[0074] According to an advantageous embodiment, the hydrophobic silica aerogel particles used in the present invention have a specific surface area per unit mass (MS) ranging from 600 to 800 m2 / g.

[0075] The silica aerogel particles used in the present invention may advantageously have a packed density r ranging from 0.02 to 0.10 g / cm3, preferably from 0.03 to 0.08 g / cm3, in particular ranging from 0.05 to 0.08 g / cm3.

[0076] In the context of the present invention, this density can be assessed according to the following protocol, known as the packed density: 40 g of powder are poured into a graduated cylinder; then the cylinder is placed on the STAV 2003® device from Stampf Volumeter; the cylinder is then subjected to a series of 2500 tampings (this operation is repeated until the difference in volume between 2 consecutive tests is less than 2%); then the final volume Vf of tamped powder is measured directly on the cylinder. The tamped density is determined by the ratio m / Vf, in this case 40 / Vf (Vf being expressed in cm3 and m in g).

[0077] According to a preferred embodiment, the hydrophobic silica aerogel particles used in the present invention have a specific surface area per unit volume SV ranging from 5 to 60 m2 / cm3, preferably from 10 to 50 m2 / cm3 and better still from 15 to 40 m2 / cm3.

[0078] The specific surface area per unit volume is given by the relation: SV = SM xr where r is the packed density expressed in g / cm3 and SM is the specific surface area per unit mass expressed in m2 / g, as defined above.

[0079] Preferably, the hydrophobic silica aerogel particles used according to the invention have an oil absorption capacity measured at the Wet Point ranging from 5 to 18 ml / g, preferably from 6 to 15 ml / g and better still from 8 to 12 ml / g.

[0080] The absorption capacity measured at the Wet Point, and noted Wp, corresponds to the quantity of oil that must be added to 100 g of particles to obtain a paste homogeneous.

[0081] It is measured according to the so-called Wet Point method or method for determining powder oil uptake described in standard NF T 30-022. It corresponds to the quantity of oil adsorbed on the available surface of the powder and / or absorbed by the powder by measuring the Wet Point, described below: A quantity m = 2 g of powder is placed on a glass plate and then the oil (isononyl isononanoate) is added drop by drop. After adding 4 to 5 drops of oil to the powder, mix with a spatula and continue adding oil until conglomerates of oil and powder form. From this point on, the oil is added one drop at a time and the mixture is then kneaded with the spatula. The addition of oil is stopped when a firm and smooth paste is obtained. This paste should spread on the glass plate without cracking or lumps forming. The volume Vs (expressed in ml) of oil used is then noted. The oil uptake corresponds to the ratio Vs / m.

[0082] The aerogels used according to the present invention are hydrophobic silica aerogels, preferably silylated silica (INCI name: SILICA SILYLATE).

[0083] By “hydrophobic silica” is meant any silica whose surface is treated with silylating agents, for example with halogenated silanes such as alkylchlorosilanes or silazanes, so as to functionalize the OH groups with Si-Rn silyl groups, for example trimethylsilyl groups.

[0084] Concerning the preparation of surface-modified hydrophobic silica aerogel particles by silylation, reference may be made to document US 7,470,725.

[0085] Particles of hydrophobic silica aerogels modified on the surface by trimethylsilyl groups will preferably be used, preferably with the INCI name SILICA SILYLATE.

[0086] As hydrophobic silica aerogels which can be used in the invention, mention may be made, for example, of the aerogel marketed under the name VM-2260® or VM-2270® (INCI name: SILICA SILYLATE), by the company Dow Corning, the particles of which have an average size of approximately 1000 microns and a specific surface area per unit of mass ranging from 600 to 800 m2 / g.

[0089] Silica aerogel particles, in particular silylated silica aerogel, may be present in a composition according to the invention in a content ranging from 0.5 to 13%, preferably in a content ranging from 1 to 5% by weight, in particular ranging from 1 to 3% by weight relative to the total weight of the composition.

[0090] Silicone emulsifying surfactants with HLB < 8.0

[0091] The composition of the invention contains at least one silicone emulsifying surfactant with an HLB of less than or equal to 8.0.

[0092] For the purposes of the present invention, the term "emulsifying surfactant" means an amphiphilic surfactant compound, i.e. one having two parts of different polarity. In general, one is lipophilic (soluble or dispersible in an oily phase), the other is hydrophilic (soluble or dispersible in water). Emulsifying surfactants are characterized by the value of their HLB (Hydrophilic Lipophilic Balance), the HLB being the ratio between the hydrophilic part and the lipophilic part in the molecule. The term HLB is well known and is described for example in The HLB System. A time-saving guide to Emulsifier Selection (published by ICI Americas Inc; 1984). For emulsifying surfactants, the HLB is less than or equal to 8.0 for the preparation of W / O emulsions. The HLB of the surfactant(s) used according to the invention can be determined by the GRIFFIN method or the DA VIES method.

[0093] For the purposes of the present invention, the term “silicone emulsifying surfactant” means a polyorganosilioxane comprising in its structure at least one hydrophilic chain, in particular at least one polyoxyalkylenated chain (i.e. polyoxyethylenated and / or polyoxypropylated) or a polyglycerolated chain.

[0094] The silicone emulsifying surfactant(s) with HLB < 8.0 is (are) preferably present in the composition at contents ranging from 0.1 to 10% by weight, more preferably from 1 to 8% by weight relative to the total weight of the composition.

[0095] Among the silicone emulsifying surfactants with HLB < 8, mention may be made of dimethicone copolyols such as that having the INCI name DIMETHICONE (and) PEG / PPG-18 / 18 DIMETHICONE (HLB = 2) sold under the brand name X-22-6711D® by the company SHIN ETSU, alkyl-dimethicone copolyols such as Cetyl Dimethicone copolyol such as CETYL PEG / PPG-10 / 1 DIMETHICONE (HLB = 5) such as the product sold under the name AB IL EM 90® by the company Evonik and the mixture of cetyl dimethicone copolyol, polyglycerol isostearate (4 moles) and hexyl laurate sold under the name AB IL WE 09® by the company EVONIK with the INCI name: POLYGLYCERYL-4 ISOSTEARATE (AND) CETYL PEG / PPG-10 / 1 DL METHICONE (AND) HEXYL LAURATE.

[0096] According to a particular form, the composition of the invention comprises at least one mixture of silicone emulsifying surfactants with HLB < 8.0 which is a mixture of DIMETHICONE, PEG / PPG-18 / 18 DIMETHICONE and CETYL PEG / PPG-10 / 1 DIMETHICONE and more particularly a mixture of DIMETHICONE, PEG / PPG-18 / 18 DIMETHICONE and CETYL PEG / PPG-10 / 1 DIMETHICONE and PO-LYGLYCERYL-4 ISOSTEARATE.

[0097] According to a particular form of the invention, the silicone emulsifying surfactant with HLB < 8.0 can be chosen from emulsifying silicone elastomers.

[0098] By "silicone elastomer" is meant a flexible, deformable organopolysiloxane having viscoelastic properties and in particular the consistency of a sponge or a flexible sphere. Its modulus of elasticity is such that this material resists deformation and has a limited capacity for extension and contraction. This material is capable of returning to its original shape following stretching.

[0099] The emulsifying silicone elastomer may be chosen from polyoxyalkylenated silicone elastomers, polyglycerolated silicone elastomers, and mixtures thereof. Polyoxyalkylenated silicone elastomers

[0100] The polyoxyalkylenated silicone elastomer is a crosslinked organopolysiloxane which can be obtained by crosslinking addition reaction of diorganopolysiloxane containing at least one hydrogen bonded to silicon and of a polyoxyalkylenated having at least two ethylenically unsaturated groups.

[0101] Preferably, the polyoxyalkylenated crosslinked organopolysiloxane is obtained by crosslinking addition reaction (A1) of diorganopolysiloxane containing at least two hydrogens each bonded to a silicon, and (Bl) of polyoxyalkylenated having at least two ethylenically unsaturated groups, in particular in the presence (Cl) of platinum catalyst, as for example described in patents US5236986 and US5412004.

[0102] In particular, the organopolysiloxane can be obtained by reaction of polyoxyalkylene (in particular polyoxyethylene and / or polyoxypropylene) with dimethylvinylsiloxy terminations and of methylhydrogenopolysiloxane with trimethylsiloxy terminations, in the presence of a platinum catalyst.

[0103] The organic groups bonded to the silicon atoms of the compound (Al) may be alkyl groups having 1 to 18 carbon atoms, such as methyl, ethyl, propyl, butyl, octyl, decyl, dodecyl (or lauryl), myristyl, cetyl, stearyl; substituted alkyl groups such as 2-phenylethyl, 2-phenylpropyl, 3,3,3-trifluoropropyl; aryl groups such as phenyl, tolyl, xylyl; substituted aryl groups such as phenylethyl; and substituted monovalent hydrocarbon groups such as an epoxy group, a carboxylate ester group, or a mercapto group.

[0104] The compound (Al) can thus be chosen from methylhydrogenopolysiloxanes with trimethylsiloxy endings, dimethylsiloxane-methylhydrogenosiloxane copolymers with trimethylsiloxy endings, cyclic dimethylsiloxane-methylhydrogenosiloxane copolymers, dimethylsiloxane-me- ethylhydrogensiloxane-laurylmethylsiloxane with trimethylsiloxy ends.

[0106] Advantageously, the polyoxyalkylenated silicone elastomers can be formed from divinyl compounds, in particular polyoxyalkylenates having at least two vinyl groups, reacting with Si-H bonds of a polysiloxane.

[0107] The polyoxyalkylenated silicone elastomer according to the invention is preferably mixed with at least one hydrocarbon oil and / or one silicone oil to form a gel. In these gels, the polyoxyalkylenated elastomer may be in the form of non-spherical particles.

[0108] Polyoxyalkylenated elastomers are notably described in patents US5236986, US5412004, US5837793, US5811487.

[0111] We can also cite the product sold under the name Dow Corning EL-7040 Hydro Elastomer Blend® by the company DOW CORNING for the compound with the INCI name: PEG-12 Dimethicone / PPG-20 Crosspolymer. Polyglycerolated silicone elastomers

[0112] The polyglycerolated silicone elastomer is a crosslinked organopolysiloxane elastomer which can be obtained by addition crosslinking reaction of diorganopolysiloxane containing at least one hydrogen bonded to silicon and polyglycerolated compounds having ethylenically unsaturated groups, in particular in the presence of a platinum catalyst.

[0113] Preferably, the elastomeric crosslinked organopolysiloxane is obtained by crosslinking addition reaction (A) of diorganopolysiloxane containing at least two hydrogens each linked to a silicon, and (B) of glycerolated compounds having at least two ethylenically unsaturated groups, in particular in the presence (C) of platinum catalyst.

[0114] In particular, the organopolysiloxane can be obtained by reaction of a polyglycerolated compound with dimethylvinylsiloxy endings and of methylhydrogenopolysiloxane with trimethylsiloxy endings, in the presence of a platinum catalyst.

[0115] Compound (A) is the basic reagent for the formation of elastomeric organopolysiloxane and crosslinking is carried out by addition reaction of compound (A) with compound (B) in the presence of catalyst (C).

[0116] Compound (A) is in particular an organopolysiloxane having at least 2 hydrogen atoms linked to distinct silicon atoms in each molecule.

[0122] Advantageously, the sum of the number of ethylenic groups per molecule of compound (B) and the number of hydrogen atoms bonded to silicon atoms per molecule of compound (A) is at least 4.

[0123] It is advantageous that the compound (A) is added in an amount such that the molecular ratio between the total amount of hydrogen atoms bonded to silicon atoms in the compound (A) and the total amount of all ethylenically unsaturated groups in the compound (B) is in the range of 1 / 1 to 20 / 1.

[0126] The polyglycerol silicone elastomer according to the invention is generally mixed with at least one hydrocarbon oil and / or one silicone oil to form a gel. In these gels, the polyglycerol elastomer is often in the form of non-spherical particles.

Powdered coloring matter

[0130] According to a particular embodiment of the invention, the composition additionally comprises at least one pulverulent coloring material.

[0131] The powdery coloring materials can be chosen from coloring pigments, pearlescent agents, optical effect pigments and their mixtures.

[0132] The term “pigments” means white or colored particles, mineral or organic, insoluble in an aqueous medium, intended to color and / or opacify the composition and / or the resulting deposit.

[0133] According to a particular embodiment, the pigments used according to the invention are chosen from mineral pigments.

[0134] By "mineral pigment" is meant any pigment that meets the definition of the Ullmann encyclopedia in the inorganic pigment chapter. Among the mineral pigments useful in the present invention, mention may be made of zirconium or cerium oxides, as well as zinc, iron (black, yellow or red) or chromium oxides, manganese violet, ultramarine blue, chromium hydrate and ferric blue, titanium dioxide, metal powders such as aluminum powder and copper powder. The following mineral pigments may also be used: Ta2O5, Ti3O5, Ti 2O3, TiO, ZrO2 in mixture with TiO2, ZrO2, Nb2O5, CeO2, ZnS.

[0135] The size of the pigment useful in the context of the present invention is generally greater than 100 nm and can range up to 10 qm, preferably from 200 nm to 5 qm, and more preferably from 300 nm to 1 qm.

[0136] According to a particular form of the invention, the pigments have a size characterized by a D

[50] greater than 100 nm and which can range up to 10 qm, preferably from 200 nm to 5 qm, and more preferably from 300 nm to 1 qm.

[0137] The sizes are measured by static light scattering using a commercial granulometer of the MasterSizer 3000® type from Malvem, making it possible to understand the particle size distribution of all the particles over a wide range from 0.01 qm to 1000 qm. The data are processed on the basis of the classical Mie scattering theory. This theory is the most suitable for size distributions ranging from submicron to multi-micron, it makes it possible to determine an “effective” particle diameter. This theory is notably described in the work of Van de Hulst, HC, “Light Scattering by Small Particles”, Chapters 9 and 10, Wiley, New York, 1957.

[0138] D

[50] represents the maximum size that 50% by volume of the particles has.

[0139] In the context of the present invention, the mineral pigments are more particularly iron oxides, titanium dioxides, and mixtures thereof. By way of example, mention may be made more particularly of titanium dioxides and iron oxides, coated with aluminum stearoyl glutamate, for example marketed under the reference NAI® by the company MIYOSHI KASEI.

[0140] As mineral pigments which can be used in the invention, mention may also be made of nacres.

[0141] By “mother-of-pearl” is meant colored particles of any shape, iridescent or not, in particular, produced by certain molluscs in their shell or synthesized and which present a color effect by optical interference.

[0142] The nacres may be chosen from pearlescent pigments, such as titanium mica coated with iron oxide, titanium mica coated with bismuth oxychloride, titanium mica coated with chromium oxide, titanium mica coated with an organic dye, as well as pearlescent pigments based on bismuth oxychloride. They may also be mica particles on the surface of which are superimposed at least two successive layers of metal oxides and / or organic coloring materials.

[0143] According to a particular embodiment, the pigments used according to the invention are chosen from mineral pigments.

[0144] Examples of mother-of-pearls that may also be mentioned include natural mica coated with titanium oxide, iron oxide, natural pigment or bismuth oxychloride.

[0145] The mother-of-pearls can more particularly have a yellow, pink, red, bronze, orange, brown, gold and / or coppery color or reflection.

[0146] Among the pigments that can be used according to the invention, mention may also be made of those with an optical effect different from a simple conventional tint effect, that is to say unified and stabilized as produced by conventional coloring materials, such as, for example, monochromatic pigments. For the purposes of the invention, "stabilized" means devoid of any effect of variability of the color with the angle of observation or in response to a change in temperature.

[0147] For example, this material may be chosen from metallic sheen particles, goniochromatic coloring agents, diffracting pigments, thermochromic agents, optical brightening agents, as well as fibers, in particular interference fibers. Of course, these different materials may be combined so as to provide the simultaneous manifestation of two effects, or even a new effect in accordance with the invention.

[0148] According to a particular embodiment, the composition according to the invention comprises at least one uncoated pigment.

[0149] According to another particular embodiment, the composition according to the invention comprises at least one pigment coated with at least one lipophilic or hydrophobic compound.

[0150] This type of pigment is particularly advantageous. To the extent that they are treated with a hydrophobic compound, they exhibit a predominant affinity for an oily phase which can then carry them.

[0151] The coating may also comprise at least one additional non-lipophilic compound.

[0152] For the purposes of the invention, “coating” a pigment according to the invention generally designates the total or partial surface treatment of the pigment with a surface agent, absorbed, adsorbed or grafted onto said pigment.

[0153] The surface-treated pigments may be prepared according to surface treatment techniques of a chemical, electronic, mechanochemical or mechanical nature well known to those skilled in the art. Commercial products may also be used.

[0154] The surfactant can be absorbed, adsorbed or grafted onto the pigments by solvent evaporation, chemical reaction and creation of a covalent bond.

[0155] According to one variant, the surface treatment consists of a coating of the pigments.

[0156] The coating may represent from 0.1% to 20% by weight, and in particular 0.5% to 5% by weight of the total weight of the coated pigment.

[0157] The coating can be carried out for example by adsorption of a liquid surface agent on the surface of the solid particles by simple mixing with stirring of the particles and said surface agent, optionally hot, prior to the incorporation of the particles into the other ingredients of the makeup or care composition.

[0158] The coating can be carried out for example by chemical reaction of a surfactant with the surface of the solid pigment particles and creation of a covalent bond between the surfactant and the particles. This method is notably described in US patent 4,578,266.

[0226] The components of phase Al were weighed and the mixture was stirred at 85°C to obtain a homogeneous phase, then cooled to 65°C.

[0227] Then the components of A2 were weighed and introduced into Al, and the whole was cooled to 30°C. The components of A3 were then added,

[0228] The previously prepared aqueous phase B was emulsified in phase A with stirring for 20 minutes at 2500 rpm.

[0229] To prepare C, the pigments were ground in an air jet mill with 11.1% of their weight in synthetic fluorphlogopite. Then C was introduced into the A+B emulsion with stirring for 10 minutes at 1500 rpm.

[0230] Unlike Example 1 according to the invention, Example 6 outside the invention with a non-silicone emulsifying surfactant showed a surface phase shift which appeared after 1 month at room temperature, which was accentuated when the emulsion was stored at a higher temperature, for example, at 37°C.

[0231] A panel of 14 people tested the foundations, on the face, with a quantity of 0.075 ml of each example.

[0232] The following cosmetic criteria were rated on a scale of 0 to 15. The higher the rating, the greater the cosmetic effect.

[0233] The results obtained are shown in the following table.

[0234] [Tables2] Evaluated criteria example 1 according to the invention example 2 comparative example 3 comparative example 4 comparative example 5 comparative Ease of spreading during application 11 8 14 6 14 Speed of drying 7 2 3 12 1 Powdery dry skin effect 2 minutes after application 9 6 3 4 6 Oily skin 2 minutes after application 6 14 10 7 9 Slippery skin 2 minutes after application 9 10 6 5 13 Soft skin 2 minutes after application 12 9 6 6 13 Film present 2 minutes after application 9 12 14 13 7 Homogeneity of the makeup result 13 12 13 10 10

[0235] Example 1 according to the invention presented a good compromise of all the cosmetic criteria tested, unlike: - example 2 outside the invention not containing volatile alkane (Isododecane) which was considered to take too long to dry, leaving a relatively oily film on the skin after drying; - example 3 outside the invention not containing non-cyclic volatile silicone oil (DIMETHICONE 2 est) produced a film that was not very soft, not very slippery and did not leave a dry, powdery sensation; - example 4 outside the invention not containing C15-19 Alkane produced a film that was not very soft, not very slippery, a less homogeneous makeup result, not leaving a dry powdery sensation; - example 5 outside the invention not containing hydrophobic silica aerogel SILICA SILYLATE was judged to take too long to dry, with a passable dry powdery sensation and a less uniform makeup result.
